BACKGROUND

1. Field of the Invention

The present invention generally relates to combustion systems forenhancing efficiency as streams of laminar air and fuel mix. Moreparticularly, but not by way of limitation, the present inventionrelates to a combustion system for generating an optimized combustionstream by directing a stream of preconditioned laminar air mixed with afuel through a combination of stoichiometric combustion stagingarrangements and refractory units.

2. Description of Related Art

The general concept of low nitrogen-oxide (NOx) burners is to produce aflame that provides heat energy though a high efficiency combustionprocess with minimal waste products arising from the combustion, namelyoxides of nitrogen of which form the basis for environmental pollutionsuch as acid rain and smog. The resulting heat energy is used in avariety of industrial applications such as for boilers in energygeneration; for furnaces employed in applications requiring high heatsuch as smelting metals, distilling chemicals, petrochemicals and gas;paper manufacturing; and for flaring oil and gas wells. Similarly, such“high efficiency” burners seek to minimize a combination of othercombustion waste products in addition to NOx such as oxides of carbon(COx) and total hydrocarbons (THC) among others to comply with federaland international governmental requirements especially for globalwarming prevention as well as to conserve natural resources bymaximizing the burn efficiency of the requisite raw materials forcombustion.

Presently, many high efficiency burners require various swirlingtechniques to maximize the efficiency of a high efficiency burner.Swirling is a widely used mixing process for homogenizing an air fuelmixture in the combustion process by which atomized fuel is introducedinto a turbulent stream of air. However, various swirling techniques areoften non-uniformly applied across the entire combustion chamber.Detrimentally, fuel and air can become drawn apart from the air fuelmixture to thereby compromise combustion efficiency as well as to spreadwaste fuel throughout the combustion chamber which requires routinelytaking the high efficiency burner out of commercial operation to performpreventative maintenance for structural damage. Moreover, turbulent orswirled air provides an aerodynamic drag-effect that generallyinterrupts the rate at which air is initially supplied to a combustionchamber, and therefore consequently decreasing the operationalefficiency of the burner. Furthermore, costly and often bulky low-wasteemissions monitoring equipment are integrated with effluent towers ofcurrent high efficiency burner systems to ensure operational efficiency.Additional costs incur as emissions monitoring equipment shorten theoperational time of such burners to ensure overall operation withinlow-waste emission requirements.

Unfortunately, there is no known device or method for successfullyproviding a “high efficiency” combustion system for leaving negligiblewaste products for sustained use with industrial applications withoutuse of swirling techniques or derivations of swirling techniques.Therefore, a need exists for a system and method for generating anoptimized combustion stream by directing a stream of preconditionedlaminar air with a fuel through a combination of stoichiometriccombustion staging arrangements and refractory units. There is also aneed for a system and method for quickly and accurately increasingcombustion efficiency for a various applications through linking aseries of interchangeable reaction efficiency modules to the system.Many other problems and disadvantages of the prior art will becomeapparent to one skilled in the art after comparing such prior art withthe present invention as herein described.

SUMMARY

Aspects of the present invention are found in a laminar flow burnersystem having a combustion manifold for establishing a combustionprocess that generates a high efficiency stream of heat energy. Thelaminar flow burner system includes a supply input module coupled to thecombustion manifold and provides fuel and laminar streams of airthereto. The combustion manifold includes at least one air-fuel mixingsystem, one stoichiometric unit, and one refractory unit each coupled toone another. A first combustion stream is established at the air-fuelmixing chamber system as fuel is discharged from a plurality ofinjectors to mix with the laminar air intake stream traveling along amixing chamber. In at least one aspect, the fuel exits from theplurality of injectors in a manner that is perpendicular to the laminarair intake stream. In one aspect, a pilot unit is provided within themixing chamber and includes an electrical resistor for igniting the fuelas the fuel contacts the hot resistor.

The stoichiometric combustion unit includes a staging passageway and astoichiometric unit body. A laminar air intake stream traveling from thesupply input module and along the staging passageway passes through astoichiometric unit body at a plurality of air intakes to meet and mixwith the first combustion stream within to thus define a secondcombustion stream for introduction from the stoichiometric unit to therefractory unit. A refractory unit body is composed of refractorymaterial to prevent absorption of heat energy to the refractory unit asthe second combustion stream travels across a refractory passageway todefine a third combustion stream. In one aspect, the third combustionstream exits the laminar burner system to thereby define an energyoutput for use with an energy consumption system.

In one aspect, a method for combusting air and fuel with a burner systemusing a laminar air intake stream is appreciated as follows. A laminarair intake stream is preconditioned prior to entering a combustionmanifold of the laminar burner system. The laminar air intake stream isdirected from the supply input module to an air-fuel mixing chambersystem of the combustion manifold. The air-fuel mixing chamber systemfeatures the injector device having the plurality of injectors and thepilot unit positioned adjacent to the injector device.

In one aspect, a first combustion stream is established within themixing chamber as the fuel is ejected from the plurality of injectorsperpendicular to the laminar air intake stream and continuously ignitedby the pilot unit as the pilot unit receives a voltage.

A second combustion stream is established within the stoichiometriccombustion unit. As such, a laminar air intake stream is directed fromthe supply input module through a staging passageway to a stoichiometricunit body each of the stoichiometric combustion unit. The secondcombustion stream is established within a stoichiometric channelway asthe laminar air intake stream from the staging passageway is injectedthrough a plurality of air intakes of the stoichiometric unit body asthe first combustion stream is directed from the mixing chamber throughthe stoichiometric channelway.

The second combustion stream is directed from the stoichiometric unitbody through a refractory unit to establish a third combustion stream.The third combustion stream exits the laminar burner system to therebydefine an energy output.

In one aspect, in addition to adjusting combustion efficiency throughcontrolling the input supply of laminar air and fuel, the combustionprocess established by the combustion manifold can be adjusted toaccurately modify combustion efficiency for various industrialapplications through linking a series of interchangeable reactionefficiency modules within the combustion manifold. Moreover, one supplyinput module can be interchanged for another of differing configurationto accommodate demand for laminar air intake streams as varyingquantities of reaction efficiency modules are either added to or removedfrom the combustion manifold.

In a further aspect of the present invention, for facilitating operationof a laminar burner system, a combustion efficiency control system isintegrated with a laminar burner system. The combustion efficiencycontrol system provides operational instructions for optimizing a highefficiency combustion process in the delivery of thermal energy to anenergy consumption system coupled to the laminar burner system.

Other aspects, advantages, and novel features of the present inventionwill become apparent from the detailed description of the presentinvention when considered in conjunction with the accompanying drawings.

DETAILED DESCRIPTION

For a more complete understanding of the present invention, preferredembodiments of the present invention are illustrated in the Figures Likenumerals being used to refer to like and corresponding parts of thevarious accompanying drawings. It is to be understood that the disclosedembodiments are merely exemplary of the invention, which may be embodiedin various forms.

FIGS. 1-3, 5, and 7 generally illustrate a laminar flow burner system 5having a combustion manifold 70 for applying a combustion process thatgenerates a high efficiency stream of heat energy. The laminar flowburner system 5 includes a supply input module 20 coupled to andproviding fuel and laminar streams of air to the combustion manifold 70.The resulting high efficiency combustion stream is optimized for avariety of industrial applications such as for boilers in energygeneration including heat, mechanical, and electric energy; propulsionsystems; for furnaces employed in applications requiring high heat suchas smelting metals and alloys, distilling chemicals, petrochemicals andgas; paper manufacturing; and for flaring oil and gas wells.

Accordingly, in at least one embodiment, the combustion processestablished by the combustion manifold 70 can be adjusted to accuratelymodify combustion efficiency for various industrial applications throughlinking a series of interchangeable reaction efficiency modules 800within the combustion manifold 70 in addition to adjusting combustionefficiency through controlling the input supply of laminar air and fuel.Moreover, one supply input module 20 may be interchanged for another ofdiffering configuration to accommodate varying quantities of reactionefficiency modules 800.

In this application, the terms “air” or “atmospheric air” refer togasses surrounding the earth that provide oxygen as a fuel forcombustion. In this application, the term “false start” refers to thetermination of a combustion process as a pilot's ignition flame is blownout as a result of high fluid flow rates that arise from any combinationof air flow or fuel flow into a combustion chamber of a burner. In thisapplication, the term “stoichiometric” refers to a qualitativerelationship of air and fuel to that of remaining combustion wasteproducts, (examples referenced above such as, among others carbondioxide), after undergoing chemical transformation from a gas statethrough an oxidation process during combustion where there is negligibleor no amounts of organic carbon and other waste products left, forexample with measured carbon dioxide emissions less than one part permillion. In this application, the term “refractory” refers to a materialfor high-temperature operational use while exposed to temperatures atleast above 1,000° C. In this application, the terms N^(th) and N^(th)−1respectively refer to: for any desired number of reaction efficiencyoptimization modules, sequentially the last reaction efficiencyoptimization module in a series of reaction efficiency optimizationmodules that define a combustion manifold and a reaction efficiencyoptimization module sequentially before the last reaction efficiencyoptimization module.

Specifically as viewed in FIGS. 1-3, 5, and 7, the laminar burner system5 includes a damper 21 in fluid communication with a blower 25 such thatthe damper 21 controls the flow of atmospheric air to the blower 25. Inthat turbulent or “swirled” air techniques commonly employed by highefficiency burners provide a drag-effect that interrupts the rate atwhich air is initially supplied to a combustion chamber, the damper 21in the present invention variably controls the flow rate of atmosphericair or, optionally, oxygen responsive to the combustion process executedby the combustion manifold 70 downstream. Accordingly, in general, alaminar air delivery system 22 that includes the damper 21 and theblower 25 that cooperatively operate to generate a laminar air intakestream for the laminar burner system 5.

Referring to FIG. 1, the laminar burner system 5 includes the laminarair delivery system 22, the supply input module 20, and the combustionmanifold 70. In operation, atmospheric air or, optionally, oxygen isdrawn through the laminar air delivery system 22, across the supplyinput module 20, and then introduced to the combustion manifold 70 as alaminar air intake stream. Similarly, fuel is directed across the fueldelivery system 30, through the supply input module 20, and dischargedwithin the combustion manifold 70 to mix with the laminar air intakestream. Illustratively, in one embodiment, ten parts of laminar air toone part of fuel is mixed within the combustion manifold 70.

As shown in FIGS. 1, 3, 5, and 7, the laminar air delivery system 22includes a damper 21 for variably collecting atmospheric air. The damper21 is of a type well known in the industry. As discussed further below,to achieve optimal levels of combustion efficiency, the damper 21 in atleast one embodiment is operatively integrated with a combustionefficiency control system 888. Through efficiency signals 88 asillustrated in FIG. 5, the combustion efficiency control system 888regulates the rate of atmospheric air collection by the damper 21.

Atmospheric air collected by the damper 21 then travels across adelivery line 23 to a blower 25. Although shown positioned in FIG. 3 ata 90° angle relative to the blower 25, those of ordinary skill in theart will readily recognize that the delivery line 23 can be positionedat any angle with respect to the blower 25.

The blower 25 operatively accelerates the air toward the combustionmanifold 70. The blower is of a type widely used in the industry, suchas a centrifugal blower or fan. Air is pushed by the blower 25 throughan air feed line 27 toward the supply input module 20. In at least oneembodiment, the air feed line 27 is a conduit. In another embodiment,the air feed line 27 is a tube. With the air exiting the blower 25, theair feed line 27, in part, operatively establishes a laminar air flowstream for use with the combustion process applied within the combustionmanifold 70. The air feed line 27 couples to the supply inlet chamber 20via the air receiving port 28. The air receiving port 28 provides asealed interface for fluid communication between the air feed line 27and the supply inlet chamber 20.

Referring to FIGS. 1, 3, and 5, the fuel is directed across the fueldelivery system 30. In at least one embodiment, the fuel includes one ormore fuels selected from the group consisting of: natural gas, processedmethane, and natural gas liquids such as propane, butane, pentane, heavyfuel oil, light distillate oil and biogas. Those of ordinary skill inthe art will readily recognize any fuel suitable for combusting with airor oxygen as the laminar burner system 5 operates in either low or highoxygen environments.

As illustrated in FIGS. 3 and 5, the fuel delivery system 30 includes afuel passageway 34. The fuel passageway 34 is a hollow body forchanneling fuel to the combustion manifold 70. In one embodiment, thefuel passageway 34 comprises a tube. In one embodiment, the fuelpassageway 34 comprises a conduit. In operation, fuel within the fuelpassageway 34 travels from a fuel source (not shown) toward the supplyinput module 20. Optionally, as discussed further below in reference toFIG. 5, a fuel controller unit 74 features a fuel passageway valve 74 acoupled to the fuel passageway 34 to variably supply fuel to thecombustion manifold 70.

The supply input module 20 features an alignment plate 72 by which thefuel passageway 34 is aligned and secured thereto. Specifically, in FIG.1, the center of the alignment plate 72 defines an alignment axis 777 bywhich the fuel passageway 34 is positioned and mounted to the alignmentplate 72 with respect to the alignment axis 777.

Accordingly, fuel travels from the supply input module 20 toward thecombustion manifold 70 within a hollow bodied, injector device 31 as theinjector device 31 provided by the fuel delivery system 30 extendsoutwardly from the alignment plate 72. In particular, shown in FIG. 1,the injector device 31 extends from alignment plate 72 along an air-fuelmixing chamber system 40 provided by the combustion manifold 70. Thoseof ordinary skill in the art will readily recognize that the injectordevice 31 can either be an integral portion of the fuel passageway 34 orseparate unit in fluid communication with the fuel passageway 34.

The injector device 31 defines a plurality of injectors 32. In oneembodiment, the injector device 31 defines a multiplicity of injectors32, such as greater than five hundred injectors. Optionally, tofacilitate a desired overall aerodynamic configuration for the injectordevice 31, at least one mixing outlet combustion enhancer 33 couples toand is rendered in fluid communication with the injector device 31thereby enhancing combustion for the laminar flow burner system 5. Forexample, as shown for the embodiment of FIG. 1, the mixing outletcombustion enhancer 33 comprises a conic configuration that couples tothe flat end of a tube defining the injector device 31 to preventaccumulation of low pressure at the flat end thereby further promotingthe mixture of fuel with the laminar stream of air within the air-fuelmixing chamber.

In operation, fuel traveling within the injector device 31 exits throughthe injectors 32 to mix with a laminar air intake stream near theinjector device 31 as the laminar air intake stream travels the alongthe air-fuel mixing chamber system 40. In at least one embodiment, as itdefines the centerline for both the injector device 31 and the alignmentplate 72, the alignment axis 777 is a spatial reference for orientatingthe ejected fuel as it combines with the laminar air-intake stream.Accordingly, as discussed in further detail below, fuel exits theinjector device 31 to mix with the laminar air intake stream to form afirst combustion stream. The fuel exits the injector device 31perpendicular to the laminar air-intake stream traveling along theair-fuel mixing chamber system 40 to define a first combustion stream.Specifically, the positive pressure of air within the air-fuel mixingchamber system 40 is low and slow moving such that fuel exits theinjector device 31 perpendicular to the laminar air-intake stream. Inone alternative embodiment, the fuel exits the injector device 31substantially perpendicular to the laminar air-intake stream travelingalong the air-fuel mixing chamber system 40 to define a first combustionstream.

Shown in FIG. 3, the alignment plate further defines a plurality ofinlet ports 29 that are variably exposed via inlet actuators 89 toselectively supply the laminar air-intake stream to the combustionmanifold 70 at a desired quantity and flow rate. As shown, each inletport 29 is characteristically small and narrow relative to the alignmentplate 72 and configured to establish laminar fluid flow therethrough. Tothereby increase energy output of the laminar burner system 5, those ofordinary skill in the art will readily recognize any suitable, wellknown size and configuration of each inlet port 29 to increase eitherthe amount or flow rate of the laminar air flow stream flowingtherethrough.

Illustratively, in FIGS. 1, 3, 3 a, and 5, a plurality of first inletports 29 a and a plurality of second inlet ports 29 b correspondinglysupply laminar streams of air from the supply input module 20 to theair-fuel mixing chamber system 40 and a stoichiometric combustion unit50, respectively. In the illustration, each first and second inlet port29 a, 29 b is operatively engaged with a corresponding sealing door 89′from a respective inlet actuator 89. The sealing door 89′ is renderedfrom a closed position to an open position to expose the correspondingfirst and second inlet ports 29 a, 29 b for flow of the laminarair-intake stream therethrough. As the sealing door 89′ moves from aclosed position toward an open position, air flow through thecorresponding inlet port 29 proportionately increases to operativelyincrease the energy output of the laminar burner system 5.

In one embodiment, the inlet actuator 89 comprises a linear actuator ofa type well known in the industry for variably rendering the sealingdoor 89′ to expose the first inlet port 29 a for selectively permittingfluid flow of the laminar air-intake stream therethrough and toward theair-fuel mixing chamber system 40. Similarly, in the continuingillustration, the inlet actuator 89 renders the sealing door to variablyopen the second inlet port 29 b for permitting fluid flow of laminar airintake stream therethrough and toward the stoichiometric combustion unit50. As discussed further below in reference to FIG. 5, the inletactuator 89 is responsive to efficiency signals 88 for variablycontrolling the flow rate of the laminar air-intake stream to optimizecombustion efficiency.

The supply input module 20 further includes an air receiving port 28.Operatively, the supply input module 20 receives air from the air feedline 27 of the laminar air delivery system 22 at the air receiving port28. In one embodiment, the air receiving port 28 diffuses the airreceived from the laminar air delivery system 22 across the supply inputmodule 20.

Illustratively, the air receiving port 28 for the embodiment of FIG. 7diffuses air received from the laminar air delivery system 22 across aplurality of laminar staging supply lines 199 to direct a plurality oflaminar air intake streams to the combustion manifold 70 that features aplurality of interchangeable reaction efficiency modules 800.

FIG. 3 a shows an interior viewer 26 b for observing operations withinthe air-fuel mixing chamber 40 and the supply input module 20 of FIG. 3.As shown, the interior viewer 26 b is composed of either transparent orsemi-transparent material, such as, among others, semi-transparenttinting and partial mirroring. The interior viewer 26 b is held in placeand positioned within the supply input module 20 by a viewer support 26a. In operation, an observer can identify many critical aspects relatingto combustion, such as, among others, the flame color through the inletports 29 a, 29 b past the alignment plate 72 to visually gaugecombustion efficiency; the general operability of each inlet actuator89; and positioning with respect to the alignment axis 77 as well as thestructural integrity of the air receiving port 28 and the fuelpassageway 34 while secured to the supply input module 20.Illustratively, in one embodiment, an observer can identify through theinterior viewer 26 b the combustion flame color adjacent to a pilotunit. In one embodiment, a boiler prism sensor of a type well known inthe industry is disposed within the mixing chamber 44 to gaugecombustion efficiency.

In one embodiment, based on the flame color viewed, an observer canmanually adjust the laminar air intake stream to correspondingly changecombustion efficiency of the laminar burner system 5. For example amongothers, by manually interfacing with the combustion efficiency controlsystem 888, the observer adjusts the corresponding inlet actuators 89 tochange the opening of the desired inlet port 29. Illustratively, in oneembodiment, ten parts of laminar air to one part of fuel is mixed withinthe combustion manifold 70 so that the color of the resulting combustionstreams reach a very bright blue color indicative of an oxidationprocess where there is no more organic carbon left so that the emissionoutput reaches a carbon dioxide level of one part per million or below.

With reference to FIGS. 1-3, 5, and 7, the combustion manifold 70 of thelaminar burner system 5 is in fluid communication with the supply inputmodule 20 to receive the laminar air intake stream and the fuel from thesupply input module 20 for establishing a high efficiency combustionprocess. The combustion manifold 70 secures to and extends outwardlyfrom the alignment plate 72. Moreover, the combustion manifold 70 ispositioned with respect to the alignment axis 777.

Operatively, for purposes of illustration, the combustion manifold 70can be divided in to a stoichiometric staging arrangement 45 and arefractory unit 60. Moreover, in FIG. 1, the stoichiometric stagingarrangement 45 includes at least one air-fuel mixing chamber system 40and at least one stoichiometric combustion unit 50.

In particular, the air-fuel mixing chamber system 40 includes a mixingchamber body 42. The mixing chamber body 42 is the innermost arrangementwithin the combustion manifold 70. The mixing chamber body 42 is fixedto the alignment plate 72 and is in fluid communication with first inletports 29 a for receiving a laminar air intake stream from the supplyinput module 20. The mixing chamber body 42 is positioned with respectto the alignment axis 777 and the injector device 31.

As shown in FIG. 1, the mixing chamber body 42 defines a mixing chamber44. In operation, fuel traveling within the injector device 31 exitsthrough the plurality of injectors 32 to mix with a laminar air intakestream near the injector device 31 as the laminar air intake streamtravels the away from the first inlet ports 29 and along the mixingchamber 44.

Referring to FIGS. 1, 3, 3 a, and 5, the air-fuel mixing chamber system40 further includes a pilot unit 35 and a combustion sensor/controllerunit 37 each positioned adjacent to the injector device 31 with respectto the alignment axis 777 and fixed to the alignment plate 72. Thesensor/controller unit 37 is electrically coupled to the pilot unit 35and the inlet actuators 89 for variably closing the respective inletports 29 and the damper 21. Moreover, the pilot unit 35 is selectivelyengaged by the sensor/controller unit 37 to ignite the nearby fuel basedon predetermined wavelengths of light detected by the sensor/controllerunit 37. The predetermined wavelengths of light correspond to the flameintensity of a first combustion stream formed within the mixing chamber44.

To avoid the abrupt, unwanted termination of combustion associated witha false start within the laminar burner system 5, the pilot unit 35remains engaged continuously or, alternatively, for periods greater thantwo minutes. Specifically, the pilot unit 35 includes an electricalresistor for igniting the fuel as the fuel contacts the hot resistor. Inone embodiment, the pilot unit 35 includes outwardly extendingprojections 35′ to facilitate rapid transfer of heat energy to the fuel.The pilot unit 35 operatively receives a voltage to generate heat energyfor any desired period. The voltage is continuously applied to engagethe pilot unit 35 thereby ensuring uninterrupted fuel ignition tooperate the laminar burner system 5 as desired.

Illustratively, in one embodiment, about one minute elapses for theresistor to warm and thus engage the pilot unit 35. The pilot unit 35receives fuel from adjacent injectors 32 to ignite and establish aflame. Accordingly, the sensor/controller unit 37 detects variouspredetermined wavelengths of light indicative of the flame color of afirst combustion stream formed within the mixing chamber 44 as the fueland the laminar air intake stream are combined. The pilot unit 35 isdisengaged by the sensor/controller 37 as the sensor/controller 37detects a predetermined wavelength of light to furthermore increase theair and fuel supply by controlling any combination of the damper 21′,the fuel passageway valve 74 a, and array of inlet ports 29. On average,in one embodiment, a period of seventy-five seconds elapses for thepilot unit 35 to fully engage and disengage in the manner describedabove.

Furthermore, in one embodiment, the electrical resistor comprises avariable resistor. In operation, the electrically engaged variableresistor ignites the fuel on contact. As such, in at least oneembodiment, the variable resistor accommodates controlling fuel ignitionbased on a timer to selectively blow out or ignite the pilot unit 35.Moreover, in one embodiment, the resistor is composed of a metal ormetal alloy, such as Ni—Cr or Al alloys, Pt, Cu, Cr metals and alloys.In another embodiment, the resistor is composed of a high temperatureceramic, such as among others nitrides, borides, carbides and oxides ofAl, Ti, Mo and Zr.

As discussed below, the sensor/controller unit 37 emits and receivesefficiency signals 88 associated with the combustion efficiency controlsystem 888. The sensor/controller unit 37 detects various predeterminedwavelengths of light indicative of the flame intensity of a firstcombustion stream formed within the mixing chamber 44 as the fuel andthe laminar air intake stream are combined. Variations in flame colorcorrespond to different levels of combustion efficiency achieved by thelaminar burner system 5. Based on measured light wavelengths, thesensor/controller unit 37 emits an efficiency signal 88 to thecombustion efficiency control system 888 to thereby adjust combustionefficiency. Accordingly, by way of illustration, the combustionefficiency control system 888 can emit an efficiency signal 88 forreceipt by the sensor/controller unit 37 or, alternatively, directly bythe inlet actuators 89 to automatically adjust the laminar air intakestream to correspondingly change combustion efficiency by changing thepilot unit's 35 period of operative engagement as a result of thesensor/controller unit 37 reading wavelengths indicative of successfulcombustion as the pilot unit 35 is engaged.

Operatively, as discussed above, a laminar air intake stream ispreconditioned prior to entering the combustion manifold 70 of thelaminar burner system 5, such as, among others, preconditioned for aspecific quantity, flow rate or temperature. In one embodiment, thelaminar air intake stream is preconditioned as ambient air, oralternatively oxygen, is forced through laminar air delivery system 22to the supply input module 20. At the air receiving port 28 of thesupply input module 20, the laminar air intake stream is separated to beprovided to the combustion manifold 70 at different stages of thecombustion process.

For example, the laminar air intake stream is divided to be provided tothe air-fuel mixing chamber system 40 and to the stoichiometriccombustion unit 50 via the first inlet ports 29 a and the second inletports 29 b, respectively. The air-fuel mixing chamber system 40 is influid communication with the supply input module 20 and includes themixing chamber 44 and the injector device 31 extending within the mixingchamber 44. At the air-fuel mixing chamber system 40, a first combustionstream is established as fuel is discharged from the injectors 32 to mixwith the laminar air intake stream traveling along the mixing chamber44. In one embodiment, the fuel exits the injector device 31perpendicular to the laminar air intake stream.

Referring to FIG. 1, the stoichiometric combustion unit 50 is in fluidcommunication with the supply input module 20 and with the air-fuelmixing chamber system 40. For the embodiment of FIG. 1, thestoichiometric combustion unit 50 includes a combustion unit body 46.The combustion unit body 46 is secured to the alignment plate 72 andpositioned with respect to the alignment axis 777 so that the air-fuelmixing chamber 40 and the injector device 35 are positioned within thecombustion unit body 46.

As shown in FIG. 1, the spatial gap between the combustion unit body 46and the mixing chamber body 42 defines a staging passageway 49 fordirecting the laminar air intake stream therethrough. Accordingly, thesecond inlet ports 29 b at the alignment plate 72 are positioned tosupply the laminar air intake stream to the staging passageway 49.

Alternatively, as shown in FIG. 5, a manifold binder body 24 can besubstituted for the above referenced combustion unit body 46 so that thespatial gap between the manifold binder body 24 and the mixing chamberbody 42 defines a staging passageway 49 for directing the laminar airintake stream therethrough. Those of ordinary skill in the art willreadily recognize various embodiments where the manifold binder body 24can either replace or complement other container bodies whilestructurally supporting the combustion manifold. For example, theembodiments of FIGS. 1 and 7 show the manifold binder body 24structurally cooperating with other container bodies to support thecombustion manifold 70 as reaction efficiency modules 800 are eitheradded or removed from the laminar burner system 5. The embodiment ofFIG. 2 shows a combination the manifold binder body 24 and the mixingchamber body 42 cooperatively providing structural support to thecombustion manifold 70. The embodiment of FIG. 5 shows the manifoldbinder body 24 as replacing other container bodies to structurallysupport the combustion manifold 70.

The stoichiometric combustion unit 50 further includes a stoichiometricunit body 51. The stoichiometric body 51 a hollow body that is in fluidcommunication with the staging passageway 49 and with the mixing chamber44. The stoichiometric unit body 51 defines a plurality of air intakes52. The laminar air intake stream travels from the staging passageway 49and enters in the stoichiometric unit body 51 through the plurality ofair intakes 52. Within a stoichiometric channelway 51 a defined by thehollow of the stoichiometric unit body 51, as shown in FIG. 2, thelaminar air intake stream from the stating passageway 49 combines withthe first combustion stream that is exiting the mixing chamber 44 andtraveling within a stoichiometric channelway 51 a to form a secondcombustion stream. In effect, the air intake stream introduced throughthe air intakes 52 acts as an oxidizer fuel for further igniting thefirst combustion stream to thus form the second combustion stream havinga higher temperature and less combustion waste products than the firstcombustion stream.

In at least one embodiment, a mixing plate 57 and a stoichiometric plate58 are disposed on opposing sides of the stoichiometric unit body 51.The mixing plate 57 and the stoichiometric plate 58 each align thestoichiometric unit body 51 with respect to the alignment axis 777 aswell as facilitate requisite fluid flow for the combustion process ofthe laminar burner system 5. In particular, the mixing plate 57 definesa mixing chamber outlet 55 in fluid communication with the mixingchamber 44 of the air-fuel mixing chamber system 40. The firstcombustion stream from the mixing chamber 44 is received at the mixingchamber outlet 55 and directed through the stoichiometric unit body 51to the refractory unit 60. Similarly, the stoichiometric plate 58defines a stoichiometric outlet 59 in fluid communication with thestoichiometric unit body 51. A second combustion stream exiting thestoichiometric unit body 51 is received at the stoichiometric outlet 55and directed through the refractory unit 60.

In summary, establishing a second combustion stream with thestoichiometric combustion unit 50 is as follows. The stoichiometriccombustion unit 50 is in fluid communication with the supply inputmodule 20 and with the air-fuel mixing chamber system 40. Thestoichiometric combustion unit 50 includes the staging passageway 49 andthe stoichiometric unit body 51. A laminar air intake stream travelingalong the staging passageway 49 passes through the stoichiometric unitbody 51 at the air intakes 52 to meet with the first combustion streamwithin to define a second combustion stream for introduction to therefractory unit 60.

Referring to FIG. 1, the refractory unit 60 is in fluid communicationwith the stoichiometric combustion unit 50. In particular, therefractory unit 60 communicates with the stoichiometric combustion unit50 at the stoichiometric outlet 59.

The refractory unit 60 features a refractory unit body 47. Therefractory unit body 47 is positioned between the stoichiometric plate58 and an outlet plate 61 at the opposing end and terminus of thelaminar burner system 5 for the embodiment of FIG. 1. In at least oneembodiment, the refractory unit body 47 is composed of refractorymaterial to prevent absorption of heat energy to the refractory unit 60as the third combustion stream travels across the refractory passageway66. In one embodiment, the refractory unit body 47 is composed ofrefractory material of a type well known in the industry, such as one ormore selected from the group consisting of: tungsten, molybdenum,aluminum oxide, aluminosilicates, silicon carbide, graphite, silica,magnesia, calcium oxides, and zirconia.

The refractory passageway 66 extends through therefractory unit 60 to communicate with the stoichiometric outlet 59 anda burner system outlet 63 defined by the outlet plate 61 at the terminusof the combustion manifold 70 of FIG. 1.

Operationally, the second combustion stream travels from within thestoichiometric unit body 51 across the refractory passageway 66 todefine a third combustion stream. In particular, in one embodiment, therefractory passageway 66 is conically shaped with the vertex emergingfrom the stoichiometric outlet 59 and the curved conic surface expandingoutwardly through the refractory unit body 51.

Similar to a jet or rocket nozzle, the volumetrically expanding conicsurface relieves high pressure build-up characteristic of the secondcombustion stream while accelerating the combustion gasses to thus forma third combustion stream. In effect, the third combustion streampromotes increased acceleration of combustion gases exiting the laminarburner system 5. Accordingly, increased exhaust acceleration providesfor the continuous drawing of the fuel, the laminar intake stream, aswell as the first, the second and the third combustion streams quicklythrough the laminar burner system without requiring additional externalwork during the combustion process. In at least one embodiment, theoutward expansion of the conic surface defining the refractorypassageway 66 is predetermined and promotes increased exhaustacceleration with negligible loss of heat energy.

Operatively, as illustrated in FIGS. 5 and 7, a refractory unit 60 iscoupled to and in fluid communication with an energy consumption system75. In one embodiment, the refractory unit 60 is releasably coupled tothe energy consumption system 75.

The laminar air intake stream in step 103 is directed from the supplyinput module 20 to an air-fuel mixing chamber system 40. The air-fuelmixing chamber system 40 features the injector device 31 having theplurality of injectors 31 and the pilot unit 35 positioned adjacent tothe injector device 31.

In step 105, a first combustion stream is established within the mixingchamber 44. In particular, the fuel is ejected from the plurality ofinjectors 31 to mix with the laminar air intake stream and ignited bythe pilot unit 35 as the pilot unit 35 receives a voltage. The laminarair intake stream is directed from the supply input module 20 through astaging passageway 49 to a stoichiometric unit body 51.

In step 107, a second combustion stream is established within thestoichiometric combustion unit 50. Specifically, the laminar air intakestream from the staging passageway 49 is injected through the pluralityof air intakes 52 of the stoichiometric unit body 51 as the firstcombustion stream is directed through the stoichiometric channelway 51a. In step 109, the second combustion stream is directed from thestoichiometric unit body 51 through a refractory unit 60 to establish athird combustion stream. In at least one exemplary method, the thirdcombustion stream exits the laminar burner system 5 to define an energyoutput for use with an energy consumption system 75.

With reference to FIG. 7, a series of interchangeable reactionefficiency modules 800 are releasably coupled with a combustion manifold70 for adjustably increasing combustion efficiency to accommodate avariety of industrial applications. In FIG. 7, a laminar burner system 5includes a supply input module 20 and a combustion manifold 70 that isin fluid communication with the supply input module 20. The supply inputmodule 20 provides fuel and a laminar air intake stream to thecombustion manifold 70.

As shown, the combustion manifold 70 includes an air-fuel mixing chamber40 in fluid communication with the supply input module 20. As describedabove, the air-fuel mixing chamber 40 includes a mixing chamber and aninjector device extending within the mixing chamber. In operation, fuelexits the injector device to mix with the laminar air intake stream toform a first combustion stream.

The combustion manifold 70 further includes a first reaction efficiencyoptimization module 800. The first reaction efficiency optimizationmodule 800 includes a first stoichiometric combustion unit in fluidcommunication with the supply input module 20 via a laminar stagingsupply line 199 provided by the air-fuel mixing chamber system 40. Thefirst stoichiometric combustion unit includes a stoichiometric unitbody, whereby a laminar air intake stream traveling along the laminarstaging supply line 199 passes through the stoichiometric unit body tomeet the first combustion stream within the stoichiometric unit body todefine a second combustion stream.

In one embodiment, the first reaction efficiency optimization module 800further includes a refractory unit. The refractory unit is in fluidcommunication with the stoichiometric combustion unit and includes arefractory passageway. In operation, the second combustion streamtravels from within the stoichiometric unit body across the refractorypassageway to define a third combustion stream.

For the embodiment of FIG. 7, the combustion manifold 70 includes asecond reaction efficiency optimization module 800′ that is releasablycoupled to the first reaction efficiency optimization module 800′ and influid communication with the supply input module 20 via staging supplylines 199. As shown, the second reaction efficiency optimization module800′ includes a stoichiometric unit body and the staging supply lines199.

Operatively, a laminar air intake stream traveling along the stagingsupply lines 199 passes through the stoichiometric unit body to meet thethird combustion stream within the stoichiometric unit body to define afourth combustion stream. Optionally, although not provided for theembodiment of FIG. 7, the second reaction efficiency optimization module800′ in other embodiments further includes a refractory unit in fluidcommunication with the stoichiometric unit body, whereby the fourthcombustion stream travels from within the stoichiometric unit bodythrough the refractory unit to define a fifth combustion stream.

Recall that “N^(th)” refers to sequentiallythe last reaction efficiency optimization module in a series of reactionefficiency optimization modules that define a combustion manifold.Therefore, in the illustration, the N^(th) reaction efficiencyoptimization module 800″ represents the last of any desired number ofreaction efficiency optimization modules after the first reactionefficiency optimization module 800 but not necessarily immediately afterthe first reaction efficiency optimization module 800, for example,among others, the N^(th) reaction efficiency optimization module 800″can represent the second or thirty-seventh reaction efficiencyoptimization module.

As shown, the N^(th) reaction efficiency optimization module 800″includes a stoichiometric unit body and staging supply lines 199.Operatively, a laminar air intake stream traveling within the stagingsupply lines 199 passes through the stoichiometric unit body to meetwith the previously generated combustion stream within thestoichiometric unit body to define an N^(th)−1 combustion stream.

The N^(th) reaction efficiency optimization 800″ module further includesa refractory unit. The refractory unit is in fluid communication withthe stoichiometric combustion unit and includes a refractory passageway.In operation, the N^(th)−1 combustion stream travels from within thestoichiometric unit body across the refractory passageway to define anN^(th) combustion stream. Accordingly, a desired combustion stream or,as referenced in the continuing illustration, N^(th) combustion streamproduced by the laminar burner system 5 defines an energy output. Theenergy output is delivered to an energy consumption system 75 for usewith a wide variety of industrial applications.

Furthermore, in one embodiment, a supply input module 20 of oneconfiguration can be exchanged for another of differing configuration toaccommodate demand for laminar air intake streams as varying quantitiesof reaction efficiency modules are either added or removed from thecombustion manifold to achieve a desired combustion output. The supplyinput module 20 includes an air receiving port 28, an alignment plate72, and a plurality of laminar staging supply lines 199 positionedtherebetween.

FIG. 7 a shows a plurality of laminar staging supply lines 199 extendingoutwardly from the air receiving port 28. In effect the laminar stagingsupply lines 199 and the above referenced staging passageway 49 areidentical in that they each operate to provide laminar air intakestreams from the supply input module 20 to the combustion manifold 70.In one embodiment, the staging passageway 49 is integral with thecombustion manifold 70 whereas the laminar staging supply lines 199 areconfigured to be removable from the combustion manifold 70.

The air receiving port 28 includes a plurality of sealed openings 28′.In operation, each seal from the sealed openings 28′ can be eitherremoved or added to accommodate insertion of a corresponding laminarstaging supply line 199 at the exposed opening to thus receive a laminarair intake stream from the air receiving port 28. Seals can be removedor added depending on the desired quantity of laminar staging supplylines 199 for delivering laminar air intake streams to the combustionmanifold 70.

One supply input module with one predetermined quantity of sealedopenings 28′ can be interchanged with another supply input module with adifferent predetermined quantity of sealed openings 28′. Thus, onesupply input module for supplying a predefined number of laminar stagingsupply lines to the combustion manifold is interchangeable with anothersupply input module for supplying a different number of laminar stagingsupply lines.

The laminar air intake stream from the supply input module 20 isdirected to an air-fuel mixing chamber system 40 that includes a pilotunit and an injector device positioned adjacent to the pilot unit andhaving a plurality of injectors. The laminar air intake stream ispreconditioned prior to entering a combustion manifold 70 of the laminarburner system 5. A first combustion stream is established within themixing chamber in the same manner described above.

Another laminar air intake stream is directed from the supply inputmodule 20 through a laminar staging supply line 199 to a stoichiometriccombustion unit of the first reaction efficiency optimization module800.

In effect, combustion streams will be sequentially generated dependingon the number of reaction efficiency optimization modules desired toarrive at a combustion stream for receipt by the N^(th) reactionefficiency optimization module. Those of ordinary skill in the art willreadily recognize that the laminar air intake stream can meet with anydesired number of combustion streams before lastly defining an N^(th)combustion stream. In at least one embodiment, the N^(th) combustionstream 800″ exits the laminar burner system 5 to define an energy outputfor use with an energy consumption system.
